Air Pollution/Climate Change Effects on Plants: General Topics
Plants react biochemically to ozone in three phases: with constitutive chemicals in the apoplastic fluid and cell membranes; by forming messenger molecules by the affected constitutive materials (ethylene); and by responding to the messenger molecules with pathogenic RNAs and proteins. For instance, plant reactions with ozone result in constitutive molecules such as the ozonolysis of ethylene i...
متن کاملEffects of climate change on water use efficiency in rain-fed plants
Water use efficiency (WUE) reflects the coupling of the carbon and water cycles and is an effective integral trait for assessing the responses of vegetated ecosystems to climate change. In this study, field experiments were performed to examine leaf WUE (WUEleaf) in response to changes in CO2 concentration and other environmental variables, including soil moisture and air temperature. We al...
متن کاملExtinction debt of high-mountain plants under twenty-first-century climate change
Quantitative estimates of the range loss of mountain plants under climate change have so far mostly relied on static geographical projections of species’ habitat shifts1–3. Here, we use a hybrid model4 that combines such projections with simulations of demography and seed dispersal to forecast the climate-driven spatio-temporal dynamics of 150 highmountain plant species across the European Alps...
متن کاملContrasting Effects of Extreme Drought and Snowmelt Patterns on Mountain Plants along an Elevation Gradient
Despite the evidence that increased frequency and magnitude of extreme climate events (ECE) considerably affect plant performance, there is still a lack of knowledge about how these events affect mountain plant biodiversity and mountain ecosystem functioning. Here, we assessed the short-term (one vegetation period) effects of simulated ECEs [extreme drought (DR), advanced and delayed snowmelt (...
متن کاملEffects of Autumn and Spring Heat Waves on Seed Germination of High Mountain Plants
Alpine plants are considered to be particularly vulnerable to climate change and related extreme episodes, such as heat waves. Despite growing interest in the impact of heat waves on alpine plants, knowledge about their effects on regeneration is still fragmentary. Recruitment from seeds will be crucial for the successful migration and survival of these species and will play a key role in their...
